Using Long Range Forecasts Correctly...

There are many models that are available to weather enthusiasts and professional forecasters to use. Some are short range and a few are long range going out 15+ days. The details in anything put past 5 days is suspect and anything out beyond 10 days is almost useless.

So while the details are useless the patterns are priceless. Those patterns show cold shots, warming trends, moisture flow, changes to the jet stream and many other things. So the tip is to get excited from the pattern but not in the details.
